phy: qcom-qmp-pcie: Fix sm8450_qmp_gen4x2_pcie_pcs_tbl[] register names
[ Upstream commit 883aebf6e1ea88145d64dcf940dbcb5181313338 ]
sm8450_qmp_gen4x2_pcie_pcs_tbl[] contains the init sequence for PCS
registers of QMP PHY v5.20. So use the v5.20 specific register names.
Only major change is the rename of PCS_EQ_CONFIG{2/3} registers to
PCS_EQ_CONFIG{4/5}.
